SOLRIDER® technical background

  • The basic principle of the solar panel is to generate power by the photovoltaic effect using photons, and since the electromotive force is generated by sunlight being irradiated on the panel surface, even if the power generation efficiency is high, dirt and dirt If light is obstructed due to adhesion or other problems, power generation efficiency will be reduced or incapacity will occur.

  • Therefore, in addition to pollution of the panel surface due to wind and rain, snow cover, bird droppings, pollen and sand mud, natural disasters such as ash fall due to eruption, the panel surface is contaminated and direct sunlight is blocked, Because it will be difficult to sustain, regular cleaning of the solar panel is essential.

As a technique to solve such problems
SOLRIDER® was born.

SOLRIDER® effect / feature

You can easily install the cleaning robot directly on the solar panel.

A cleaning body installed vertically movably along the moving guide rails to the left and right that are provided between the upper end and the lower end of the solar panel cleaning and cleaning the entire surface of the solar panel.

Easy to remove

The moving guide rail can be easily removed and can be carried to another array one after another.

Easy to remove

Easy to move guide rail

Since multiple urethane auxiliary wheels are provided at the contact part with the solar panel, it is possible to move the moving guide rail laterally without applying a large load to the surface of the panel.

Easy to move guide rail

Cell crack does not occur

In the EL inspection in the inspection facility, cell cracks did not occur at all even after 1,000 reciprocating cleaning of the panel surface.

The entire surface of the solar panel can be cleaned uniformly to the corner, without unevenness, and because it is filtered water, it does not add water scale.

The entire surface of the solar panel can be cleaned uniformly to the corner, without unevenness, and because it is filtered water, it does not add water scale.

SOLRIDER® has a nozzle that injects water supplied from the outside via a filter, a hose, etc. onto the surface of a solar panel.

Surprise cleaning system

The supplied water raises the dirt adhering to the solar panel and the rotating cleaning brush made of the spiral brush body cleans up the floating dirt by brushing it.

Surprise cleaning system

Complete removal of solar panel dirt

At this time, extra moisture and moisture into which the dirt is dissolved will remain on the solar panel, but the wipers wipe away this residual moisture, so that the dirt on the surface of the solar panel is completely removed.

Complete removal of solar panel dirt

Wash with two wipers

Two windscreen wipers are installed at positions sandwiching two rotating cleaning brushes. With this configuration, SOLRIDER® moving horizontally to the left or right moves the moisture containing dirt in either direction , It is possible to reciprocate and clean without leaving it on the solar panel. The wiper can also be changed from a brush shape to a rubber shape.

Dirty water during cleaning does not splash to the surrounding solar panel.

The SOLRIDER® has a chassis. The enclosure is a cover-like member that covers the cleaning body and is made of resin such as plastic.

Avoid scattering of dirt

By installing the enclosure, it is possible to prevent the scattering of dirt accompanying the rotational cleaning operation of the rotary cleaning brush, so that it is possible to efficiently clean the solar panel without contaminating other solar panels

Avoid scattering of dirt
You can make safe driving by making effective use of the edge of the side of the solar panel.

The moving guide rail is equipped with a pair of upper and lower fixing members (moving wheels) for clamping the solar panel from above and below.
The distance between the fixed members (moving wheels) installed on the top and bottom can be changed freely, so it can be installed on solar panels of all sizes.

Can be mounted on solar panels up to 6 meters long

By using the extension unit, the moving guide rail can be installed and installed on solar panels up to 6 meters above and below.

Can be mounted on solar panels up to 6 meters long

Sandwiching the solar panel from the top and the bottom so it can be cleaned safely

The solar panel installed at a steep angle by the fixed member (moving wheel) for holding the solar panel from above and below is also free to move while cleaning and SOLRIDER® slides off the solar panel It is preventing.

Sandwiching the solar panel from the top and the bottom so it can be cleaned safely
It is seven times more work speed and less than one eighth of consumption water compared with human washing work.

It is seven times more work speed and less than one eighth of consumption water compared with human washing work.

Soft nylon brush mounted on SOLRIDER® with a total length of 103 cm moves sideways smoothly at 3 km / h while rotating 20 times per second, cleaning the solar panel.

Significant reduction in cleaning time

As an example, when cleaning a 1 MW photovoltaic power generation facility by washing, brushing and wiping with human work, it took more than 14 days on average for two people.
When SOLRIDER® is used, it is possible to clean 1 MW photovoltaic facilities with only two people in two people.

Significant reduction in cleaning time

Significant reduction in water consumption

Also in the case of cleaning 1 MW photovoltaic power generation facilities, human consumption requires more than about 25,000 liters of water, but in working with SOLRIDER®, the amount of water consumed is reduced to about 3,000 liters or less of water, You can clean it.

Significant reduction in water consumption

Reduction of human errors and accidents

Using SOLRIDER® reduces the risk of lowering the amount of power generation due to unnecessary washings and uncleaning of dirty moisture, which is likely to occur in human labor, and the risk of occupational accidents due to high place work.

Reduction of human errors and accidents
